“… for without me ye can do nothing”
The work of God in the new creation is legal and vital.
Here is a simple illustration: imagine you paid for a house. After you’ve paid, it’d still take you a while to move in and settle in, but once you are handed the ‘Certificate of ownership’, it’s your house as a legal fact.
Likewise, anyone who believes in Jesus is ‘saved’.
The bible says that God, “Even when we were dead in sins, hath quickened us together with Christ, by grace ye are saved” Ephesians 2:5
Yet, we are told that we ‘will’ be saved (Acts 15:11).
That is, the moment we believe, though we are declared righteous, that salvation will be consummated when Christ returns for us and we receive new bodies in which we will live for eternity.
The point here is simply that, on one hand, our union with Christ is a reality.
However, we must yet ‘abide’ in Him. What is a legal fact must become a vital fact.
A good example is in Paul’s letter to Colosse:
“If ye then be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God. Set your affection on things above, not on things on the earth. For ye are dead, and your life is hid with Christ in God” Colossians 3:1-3.
‘Set your affection’ where you are. Be conscious of your union. This is key to your fruitfulness.
